Product Introduction RoyalPharm
Multi-effect distilled water device usually consists of two or multiple evaporators, heat exchangers, separators, preheaters, condensers, valves, meters, and control systems. Usually, the systems are 3-6 effect, each system is consists of one evaporator, one separating unite, and one preheater.
In multi-effect distilled water device, the steam (pure steam) come form each effect will be used to heat raw water, and more pure steam will be produced in the flowing effects. Pure steam condense to be injection water after heating raw water. Only the first effect evaporator need external heat in the multi-effect system. The steam produced by the last effect and the condensed water are cooled by external cooling medium. In conclusion, Multi-effect water distilled machine can save quantity of energy, as the increase of the effects, there will be more energy saved. That means, three effect device can save more energy than second effect. To keep a certain output of injection water, if you want save the consumption of fresh steam and cooling water, you must increase the effects.
Requirement for external supply RoyalPharm
1, Industry steam as fresh steam: 3-8bar;
2, raw water: purified water meeting the requirements of Chinese Pharmacopoeia, the supply of purified water must be greater than the output of Multi-effect water Distiller.
3, Cooling water: Softened water at least, or use raw water directly(to avoid scaling substance blocking)
4, Compressed air: 5.5-8bar
Main parts introduction RoyalPharm
Raw water congealed into injection water through flashing evaporation at shell and tube heat exchanger of Multi-effect evaporator. At the same time, pure steam condensed into injection water.
Industry steam flow into shell from the water inlet of first-effect evaporator to heat raw water that in tube, the liquid water condensed from industry steam flow out of evaporator.
Raw water flow from top inlet to the evaporator, and distributed evenly to form falling film, then exchange heat with steam in shell, water evaporate to be steam, steam mixed with small droplets. Mixed steam and droplets fall into separator, steam rise up under continuous pressure. Droplets separate with steam, accumulate and fall to the bottom. Pure steam flow to shell of next stage to heat water in pipe. Droplets in mixture and unevaporated water flow into next stage to continue to evaporate. By that analogy, the after evaporators follow the same principle. Evaporators after the first stage use the steam produced by former stage evaporator. Pure steam begin to condense at the second stage, and was collected and transported to shell of condenser. Pure steam produced by the last stage pass into shell of condenser and mixed with injection water.
In Multi-effect Water Distilled machine, the heat source of preheater is steam or condensed water. Steam from evaporator or steam condensation water pass into preheater shell to heat raw water in pipe. Preheater heat raw water step by step, temperature of raw water that flow condenser is more than 80ºC, raw water of this temperature must flow preheater to the end, and then pass into evaporator
There are vertical pipes inside the evaporator, raw water flow into preheater after pipes. Steam produced at last stage and injection water condensed at former evaporators flow into shell to heat raw water in pipes, injection water flow from upper condenser to following condenser, then flow into storage tank.
We usually install a 0.22μm rebreather, it can prevent vacuum inside the device when device stops running, also can prevent microbe entering into condenser, at the same time, it can release non-condensable gas and volatile impurities.
Technical key points
1 At first stage evaporator, all of the preheater are double tube plate structure, this structure can prevent cross contamination;
2 the discharge of condenser is less than 3%, there are discharge part for each evaporator and condenser;
3 there are rebreather to prevent vacuum in condenser;
4 Distilled water machine can disinfect liquid online;
5 Liquid level can be controlled at a setting degree at the first and last stage;
6 There are discharge outlet at the lowest point of each stage;
7 It can stop condensed water backing at the last stage;
8 Cooling water can regulate itself serially to keep injection water a stable temperature
9 All of the pipes are thermal insulation, reducing thermal radiation;
10 Ther are air supply protection to keep dampproof, heat proof, dust proof, and instrument cabinet separate with high voltage electricity cabinet in control cabinet.
11 Adopt paper recorder to record electricity conductivity and temperature of effluent water.
12 Conductivity meter of injection water help to test temperature.
